Like STX , WDC and SNDK

Screening Filters

1. region: ['US']

   • Purpose: Limit results to companies listed in the United States.
   • Rationale:
     • STX (Seagate) and WDC (Western Digital) are both U.S.-listed companies, so focusing on the U.S. market ensures we’re analyzing the correct firms and the correct regulatory/market environment (Fed policy, U.S. macro data, etc.).
     • SNDK (SanDisk) was a U.S.-listed stock (NASDAQ) before being acquired by Western Digital in 2016. For any historical performance or factor analysis, U.S. as the region is still the appropriate context.

2. list_exchange: ['XNYS', 'XNAS', 'XASE']

   • Purpose: Restrict the search to the main U.S. stock exchanges:
     • XNYS – New York Stock Exchange
     • XNAS – NASDAQ
     • XASE – NYSE American (formerly AMEX)
   • Rationale:
     • STX and WDC are traded on NASDAQ (XNAS), so this filter precisely targets their primary listings.
     • SNDK’s historical listing was also NASDAQ, so any legacy data or references will be tied to XNAS.
     • Filtering to these major exchanges avoids pulling in OTC, pink sheets, or foreign duplicates that might share similar tickers but are unrelated to your query.

3. user_watchlist: False

   • Purpose: Do not restrict results to a personal/custom watchlist.
   • Rationale:
     • Your question is about specific tickers (STX, WDC, SNDK), not about “from my watchlist.”
     • Leaving the watchlist filter off ensures that we can analyze these names whether or not they’re saved in any predefined list, giving a full, unbiased view of the requested stocks.

Why Results Match:

• The tickers you asked about (STX, WDC, and historically SNDK) are U.S.-listed (or were, in SNDK’s case), so region = US and XNYS/XNAS/XASE are exactly the right universe.
• Using only major U.S. exchanges targets the actual trading venues for these stocks and avoids noise from unrelated securities.
• Because we’re not filtering by any user-specific watchlist, the screener will freely include the requested tickers.

One nuance: SNDK no longer trades as an independent stock because it was acquired by Western Digital. That means a live screener may not return SNDK as an active listing, but the U.S./NASDAQ-focused filters are still the correct framework for discussing its historical performance and its role in WDC’s current fundamentals.
